Uterus Anatomy - 1 | Parts of Uterus | Abdomen

Summary

In this informative video, Mohit introduces the uterus, a crucial organ in female reproduction. He explains its role as a child-bearing structure where implantation and fetal growth occur. Located between the bladder and rectum, the uterus has a pear-like shape and specific dimensions. Mohit details its three main parts: the fundus, body, and cervix, each serving vital functions, including nutrient provision and expulsion of the fetus. The video also covers the anatomy of the cervical canal and its openings, enhancing viewers' understanding of this essential organ. Further topics will explore uterine ligaments and axis.

Takeaways

• 😀 The uterus, also known as the womb or hystra, is a crucial organ for childbearing in females.
• 👶 The primary function of the uterus is to provide a site for implantation and support the growth of the fetus.
• 📏 The uterus has a pyriform shape, commonly described as an inverted pear, with dimensions of approximately 3 inches in length, 2 inches in breadth, and 1 inch in thickness.
• 🔗 The uterus is situated between the urinary bladder and the rectum, allowing communication with the uterine tubes above and the vagina below.
• 📊 The uterus comprises three main parts: the fundus, body, and cervix, each with distinct roles and relationships with surrounding structures.
• 🔼 The fundus is the dome-shaped upper part of the uterus, where fertilization typically occurs and is covered by peritoneum.
• ⚖️ The body of the uterus is the largest section, featuring anterior and posterior surfaces that are related to the urinary bladder and the sigmoid colon, respectively.
• 🔄 The cervix is the cylindrical lower part of the uterus, with both supravaginal and vaginal sections, and contains two openings known as the internal and external os.
• 🌀 The cervical canal, shaped like a fusiform, features mucosal folds called Arbor Vitae Uteri that help close the canal.
• 📅 Future discussions will include the ligaments of the uterus and the important topic of the uterine axis.
